  1. 16. CFD analysis of a glider aircraft : Using different RANS solvers and introducing improvements in the design

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : David Perez Sancha; [2019]
    Keywords : CFD; RANS; Standard Cirrus; glider; Fluent; SU2; OpenFOAM; SST; transition; winglet.;

    Abstract : In this study, Computational Fluid Dynamics (CFD) simulations have been carried out in order to investigate and improve the performance of the Standard Cirrus glider, using different Navier-Stokes methods and solving the equations for the steady flow. The work has been divided in two parts: First, a study is performed to test the quality of the transition model (Gamma-ReTheta). READ MORE

  3. 17. CFD Analysis of Heat Transfer in an Innovative Facade System

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Christoffer Bågholt; [2018]
    Keywords : Computational Fluid Mechanics; Heat Transfer; Building Physics;

    Abstract : New innovative façade systems that are well thought out, rational, sustainable and energy efficient are needed for renovation of old buildings to drastically reduce the heat losses through walls and to improve indoor conditions. In order to achieve the above mentioned goal, new innovative modular systems that can be mounted on site with ease are an interesting alternative. READ MORE

  4. 18. CFD analysis of stepped planing vessels

    University essay from KTH/Mekanik

    Author : Toni Kokkonen; [2018]
    Keywords : Computational Fluid Dynamics CFD ; Ship hydrodynamics; Planing hull; Stepped hull; STAR-CCM ; Overset mesh; Volume of fluid VOF ; Reynolds averaged Navier-Stokes equations RANS ; Dynamic instabilities;

    Abstract : High speed planing hulls are currently widely used for example in recreational and emergency vessel applications. However, very little CFD research has been done for planing vessels, especially for those with stepped hulls. A validated CFD method for planing stepped hulls could be a valuable improvement for the design phase of such hulls. READ MORE

  5. 19. CFD Simulations of Unsteady LHA Ship Airwake in OpenFOAM

    University essay from KTH/Mekanik

    Author : Matus Cvengros; [2018]
    Keywords : ;

    Abstract : Extensive research in the past two decades has shown that flow around the sharp edges of bluff bodies, such as the superstructure of a ship, can cause large scale shear-layer separations with increased turbulence, generating a highly unsteady flow in the airwake region. Such separations affect the control margins and handling loading of a rotorcraft, mainly if operating from the vicinity of a flight deck, and therefore negatively influence the rotorcraft operating limits, which is one of the main reasons for the study of ship airwakes.

  6. 20. On Control and stabilisation of floating wind platforms with the help of CFD analysis and the Magnus effect

    University essay from KTH/Numerisk analys, NA

    Author : Georg Neumüller; [2017]
    Keywords : ;

    Abstract : With new technologies and possibilities arising both in the renewable energy sector as well as in the field of Computational Fluid Dynamics, this thesis describes the simulation of vortex- induced vibrations for floating wind turbine platforms. The aim is to control and stabilize floating wind platforms with the help of CFD and the Magnus effect. READ MORE
